Atom V has one electron in its outmost period, while atom H has three. Write simple valence bond wave functions for the diatomic molecules V2 and H2.
I think H is supposed to be a variable, not Hydrogen
Consider a ring system made up of 8 atoms (each one contributing a p atomic orbital to make 8 pi molecular orbitals). If the system is filled with 6
orbitals containing single,
electrons, there will 6
orbitals containing pairs of electrons and 1
unpaired electrons. Hint: Use a Frost Circle.
Use numbers rather than text for your answers.
44. The molecule H3* has long been speculated to exist. The interest here is that the addition
of the smallest bit of nuclear matter, a proton, now introduces additional nuclear
repulsion over the H₂ problem. The issue was whether electron distributions could lead
to a stable configuration.
a) Draw what you think would be the most stable structure for H3* and show all
the Coulombic terms (write out the potential needed for the corresponding
Schroedinger equation).
b)
Draw what you think is the least stable configure of the 3 protons and 2
electrons.
c) It is found that the structure involves the rotation of one proton around the
other two, and interchange of which proton is rotating. Offer a potential
explanation (think tunneling).
